Can black holes and naked singularities be detected in accelerators?
Abstract
We show that TeV-scale black holes produced in colliders are relatively very long-lived and, since they must be electrically neutral, they cannot be detected directly. However, either they escape from the detector and carry away a large amount of energy or in rare instances they slowly decay via the Hawking process giving rise to an isotropic (almost steady) flux of particles (a ``star'') inside the detector. Both events can be easily recognized and the latter would be an unmistakable signature for a black hole in extra dimensions. We also discuss the possible formation of naked singularities, for which although no clear phenomenology is yet available, one expects a sudden decay without a clear signal to distinguish them from other intermediate states.Keywords
